In an effort to implement some new training methods this outdoor track season with my distance runners (so as to prevent general stagnation), I've been toying with the idea of having my more advanced runners try some barefoot running -- at first it would probably be for 5 minutes at a time during post-workout or post-race cooldowns on FieldTurf, perhaps with some strides at the end. I've done a lot of reading and have come to the conclusion that barefoot running can build foot/ankle strength and help promote good running economy. Does anyone have any experience with barefoot running, and if so, has your experience been positive? Thanks!
I think you can safely ignore the alarmist cries if you avoid a few basic mistakes. What comes to mind is:
* no barefoot running on abrasive surfaces like asphalt (it takes only a few kilometres for blisters to appear and burst. I know: unfortunately, I tried);
* no barefoot running on hard surfaces, like asphalt, again (it might be possible to progressively strengthen your bones, but I am not sure. On the other hand, you can definitely get a metatarsal stress fracture in thin-soled shoes (think: 2-3 mm), but at least there are signs (feeling the shoelaces are too tight at the front of the foot, no matter how much you loosen them)).
If your plan is to have people run on grass for 15 minutes a day, I'd be surprised if serious injuries occur. Just make sure to tell them to back off if their calves/Achilles get painful. Also, I would not expect the runner's experience to make much of a difference (if only: more experience, less capacity to adapt, *maybe*). How much they heel-strike may matter much more.
Now, will it benefit them? I don't know.
It may take more than a few minutes each day to actually change the way they run.
Also, switching entirely to zero drop shoes (or barefoot running, I guess) will definitely change something in the calves. But as much as I like running in zero drop shoes, I wouldn't guarantee it will bring performance improvements. From my experience, it didn't change my race times. I think it just made me faster when going downhill. But then, you have to climb that up again on most courses, so...
About injuries in the long run: I got two issues with my Achilles (but in retrospect, if I had been more cautious when pain appeared instead of deciding to go ahead and run races...), one likely metatarsal stress fracture (totally avoidable, if only I had known what the initial symptoms meant). After that, nothing serious for almost two years, while I increased my mileage like never before (with for instance, 8 weeks at between 135-150 km per week).
So, just like running does not ruin your knees, barefoot/zero drop running is not dangerous. Switching running style is, but can be done with care. And if ever it does not bring substantial performance improvement, at least it's different and definitely fun.
